PTFE (Polytetra fluoroethylene)
About This Project
Polytetrafluoroethylene (PTFE) is a synthetic fluoropolymer of tetrafluoroethylene PTFE is a thermoplastic polymer, which is a white solid at room temperature, with a density of about 2200 kg/m3 and a melting point of 600 K (327 °C; 620 °F).It maintains high strength, toughness, and self-lubrication at low temperatures down to 5 K (−268.15 °C; −450.67 °F), and good flexibility at temperatures above 194 K (−79 °C; −110 °F)
They can, however, be vastly improved by the addition of filling materials such as glass fiber, carbon, and graphite. PTFE has almost perfect electrical properties. Its dielectric constant is minimal (2.1) as is its dielectric loss factor (0.0002), and this remains the case over a wide range of temperatures and frequencies. PTFE does not burn at an open flame but degenerates above the continuous operating temperature.
